Ah, I wish.... but your remark does suggest a new approach, although it's not quite as simple as you suggest.

Although I didn't spell it out, I did look at the provided .mc samples and the .cf files generated from them. If I could have found a simple "superset" I would have used that - but none of them actually is.

Additional point:
I originally reasoned that default-procmail-lda.mc was the most likely "best" equivalent to use; I see it supports procmail (which I'd like to use at a later point). Problem is, from the descriptions I'm not quite sure whether it merely "supports" procmail or _requires_ procmail to be installed (which I haven't done yet - one change at a time is enough!). Still, since functionally it looked closest to what I had (and want to have), that's what I used to generate a .cf file from that I hoped I could copy portions from to my original sendmail.cf. Which obviously didn't quite work...

So... Starting from the other end, as it were, I'll now have to learn how to actually create an .mc file (and maybe supporting file(s)) that will generate something equivalent (or a superset that will work). Starting from the "superset" idea, three points come up:

1. When I found out that spammers could verify email addresses on the server, I wrote support and they added a 'Opnovrfy' option to sendmail.cf for me (although they downplayed the importance of that - but I _had_ seen spammers actually using VRFY against the server). Later, studying the subject (and sendmail) a bit more, I changed that myself to 'Opgoaway'.
        => None of the (four) provided sample .mc files suggest any way for me to specify such an option. Can I do that in .mc, or would I still need to edit the generated .cf file to get the same option? If in .mc (preferred), what's the syntax for specifying this?

2. Provider added support for one extra domain for me (and were kind enough to tell me what they did); later I added another domain myself. This takes the form of 'Cwlocalhost firstdomain.com second.tld'
        => It seems .mc files do not directly support this, but I have to create an external file with the domains to be supported?
(If so, there's an equivalent, but I'll need to create an extra file, merely generating a .cf from .mc would not be sufficient.)

3. A third customization I did myself, after seeing another (access) provider's host headers specify a 'for' part in the headers. I managed to figure out how to define that in sendmail.cf.
        => Looking at the generated .cf files, it looks as though header writing _is_ actually a superset of what I have now, so that's fine.

If you (or someone) could answer or confirm these three issues for me, I can probably get to the point where I have an .mc file (plus whatever else is needed) to use to generate a replacement for my tired old sendmail.cf - and then continue from there.

Thanks for any help!
